Shaping the future of 3D interaction with virtual worlds
No full textvideo/mp4Virtual reality (VR) spontaneously evokes a set of high-endtechnologies designed to "immerse" itsusers in synthetic 3Denvironments simulated in real time by a computer. Thanks to dedicatedinterfaces such as head-mounted displays, VR applications allow usersto have powerful experiences such as being in a different place orinteracting with characters that are not physically present forreal.The first VR systems date back to the 1950s or 1960s, but a media andeconomic craze hasrecently developed, especially with the buzz around"metaverses" these massively shared virtualworlds often presented asthe "Internet of the future", in which we may one day be able toperform many human activities such as working, training, visiting,meeting, shopping, etc. Such anextraordinary promise has motivatedcolossal investments of the tech giants over the last 10 years.We aretherefore living in a pivotal and historic moment for this field,which is progressively moving towards mass applications. In this talk,we will question the next steps for VR technologies. We willfirstargue that VR is progressively bringing more physical engagement in 3Dhuman-computer interactions, for example through "haptic" technologies(tactile or force feedback) or virtual embodiment in "self-avatars"(anthropomorphic representation of oneself in a virtualenvironment).We will also focus on the current hybridization of VRtechnologies with physiological and neural interfaces, suggestingfuture interactive systems directly exploiting users' cognitivestates, and pavingthe way for even more compelling and holisticexperiences. We will illustrate our talk with some ofour latestscientific results, showing a glimpse of what could be “the future ofour 3D interactions with virtual worlds”.講演日: 2023年4月7日 4限講演場所: 情報科学棟 エーアイ大講義室(L1)vide
Practical Development of a Robot to Assist Cognitive Reconstruction in Psychiatric Day Care
Get PDFOne of the important roles of social robots is to support mental health through conversations with people. In this study, we focused on the column method to support cognitive restructuring, which is also used as one of the programs in psychiatric day care, and to help patients think flexibly and understand their own characteristics. To develop a robot that assists psychiatric day care patients in organizing their thoughts about their worries and goals through conversation, we designed the robot's conversation content based on the column method and implemented its autonomous conversation function. This paper reports on the preliminary experiments conducted to evaluate and improve the effectiveness of this prototype system in an actual psychiatric day care setting, and on the comments from participants in the experiments and day care staff.conference pape

Water splitting and CO2 reduction over an AgSr2Ta5O15 photocatalyst developed by a valence band control strategy
No full textAg+ substitution was applied to a tungsten-bronze-type metal oxide. An AgSr2Ta5O15 photocatalyst has emerged for water splitting and CO2 reduction. DFT calculation and diffuse reflection spectra revealed that the Ag d-orbital formed a new valence band, leading to a narrow band gap (3.91 eV) compared to that of NaSr2Ta5O15 (4.11 eV).journal articl
Partial Gathering of Mobile Agents in Dynamic Tori
No full textIn this paper, we consider the partial gathering problem of mobile agents in synchronous dynamic tori. The partial gathering problem is a generalization of the (well-investigated) total gathering problem, which requires that all k agents distributed in the network terminate at a non-predetermined single node. The partial gathering problem requires, for a given positive integer g (< k), that agents terminate in a configuration such that either at least g agents or no agent exists at each node. So far, in almost cases, the partial gathering problem has been considered in static graphs. As only one exception, it is considered in a kind of dynamic rings called 1-interval connected rings, that is, one of the links in the ring may be missing at each time step. In this paper, we consider partial gathering in another dynamic topology. Concretely, we consider it in n× n dynamic tori such that each of row rings and column rings is represented as a 1-interval connected ring. In such networks, when k = O(gn), focusing on the relationship between the values of k, n, and g, we aim to characterize the solvability of the partial gathering problem and analyze the move complexity of the proposed algorithms when the problem can be solved. First, we show that agents cannot solve the problem when k = o(gn), which means that Ω (gn) agents are necessary to solve the problem. Second, we show that the problem can be solved with the total number of O(gn2264 k 00B2) moves when k 00B2) moves to solve the partial gathering problem in dynamic tori when k = Θ(gn). Thus, when k 00B2) of agent moves.conference pape
